For card_grid, payload must contain a non-empty \"cards\" array. Each card must have string \"id\" and string \"title\". Optional card fields: \"subtitle\", \"image\" (URL), \"meta\" (array of {\"label\", \"value\"}), \"description\" (short string), \"details\" (array of {\"label\", \"value\"} shown in modal), \"actions\" (array of {\"label\", \"url\"}). Limit card grid to 4 cards. After rendering the grid, still give a brief text summary and ask what the user wants next."
